Yes! Its possible to change the target node of a connection at the moment but not the source.
It would be nice if you could add such a feature in the next update! Sometimes a user builds something wrong and then its a pain in the ass to reconnect all the connections with all their conditions.
Btw: Thank you again for this great product and the support, we are developing our whole framework on this plugin! 🙂 And it makes a lot of fun!! 😉
